Deformed Cross-Bedding in Tertiary-cretaceous Sandstone, Arctic Canada

B. R. Rust


Cross-beds in sandstone near Stanwell-Fletcher Lake, Somerset Island, Arctic Canada are deformed into regular structures which resemble recumbent folds. The majority of deformation axes are orientated perpendicular to the dip of undeformed cross-beds, and overturning is always in the downcurrent direction. In some cases there is a gradual transition from deformed to undeformed cross-beds in both the upcurrent and downcurrent directions. These features are considered as most satisfactorily explained by deformation due to the overriding drag of a mass of sediment moved by the current.
